While Sally and Mildred are visiting a hospital looking for a friend, Mildred witnesses a murder in another room. But when Sally and staff come back there, it's empty. Eventually, some kind of Satanic cult is involved. I'll stop there and just say this was quite scary and funny with fine turns from Werner Klemperer (yes, the former Colonel Klink of "Hogan's Heroes") and Keenan Wynn who I just also watched in an ep of "Kolchak: The Night Stalker" as well as Robert Hooks. I also liked the small part of John Fiedler as a coroner. Oh, and I also loved the music score that played throughout this particular ep. So that's a recommendation of "The Devil You Say".
